tro ALL WHOM IT MAY c'iolvcnim:

Be it known that I, STEPHEN REX,'of Orefield, in the county 0f Lehigh,and State of Pennsylvania, have invented a new and improved Safetylipck'lfor Harvesters; andI do hereby declare that the following is a full,clear, and exact description thereof, which willenable those skilled inthe art to make and use the same, reference being had to theaccompanying drawings, forming'part of this specification, in whichy'Figure l is avertical section nf vmy invention thronghfthe, line x'x,iig. 2.

Figure 2 is atop view of the same. i I

Similar letters of reference indicate corresponding prts.

Theobject of-this invention is to accomplish theinstantaneous locking ofa-reapingor mowing-machine when the driver shall fall therefrom, andthereby prevent nnyinjnry to the driver from the cutters or-knives ofthemachine. l

I In the accompanying plate oi' drawings some one cog-Wheel ofthe'gearing, connecting the drive-wheels B with the knives or cutters,is shown at D. This wheel may be keyed on theshaft of the driving-WheelsB, as shown, or may be some intermediate wheelloi` thegearing. l

A toothed locking-parli isshown at e, which-is hinged to any convenient,part ofthe frame of thernachine, as shown. l l v v A spring,f, actuatesthepawl to mesh its teeth into the teeth of the wheel D, When the levera is -liberated. This lever is pivoted by llgs b, or in any othersuitable manner, to some point on the mainframe, andv its lifting-end isbent to 'pass under the pawl to enclose it between the projections i z'of the said levert When the machine is reaping or mowing, the driverretains one foot upon the free end of the lever, and when from any causehe shall be thrown or fnll from the machine, the locking-pawl willdescend, Aand its teeth will engage with the teeth of the wheel D, andthereby stop the gearing of the cutters or knives,`

,A button, d, may 'be employed to keep the pawl raised 'when the driverwalks by the side of the machine.

In oiling'and otherwise moving about in front of the machine, it oftenoceurs'that'the horses start to move olf or run. yIl' the machine isprovided with my improvements, there will be less danger in attemptingto ston them than when the machine is not so provided. Y l

My invent-ion is simple and inexpensive, andlcan be easily applied tothe machines already in use.

l claim as new, and desire to secure by Letters Patenti The locking-pawle, lifting-lever a, and springf, substantially as vshown and described,when combined with' any toothed wheel of the gearing, operating thecutters oruknives of a. reaping or mowing-machine, all as and for thevpurpose set forth.

STEPHEN REX.
